What Can I Do if My Resin Casting Sticks to the Mould?

← Back to How to keep epoxy resin from sticking?

If your resin piece is stuck in the mould, it can be frustrating—but with a gentle approach and a few practical steps, you can often release your casting without damage.

Careful Demoulding Techniques

Avoid using any sharp or metal tools that could scratch or tear your mould. Start by carefully flexing the mould from the edges, easing the resin away. If the casting doesn’t release, soak the entire mould in lukewarm water—this may help the resin contract slightly and loosen its hold.

Prevention for Future Castings

To reduce the risk of sticking next time, always use non-stick moulds made from silicone or consider lining your mould with a specialist release film. Products like Shiny Shield Glossy Release Film can make demoulding straightforward and preserve the glossy finish of your casting. Try to remove items from the mould within 12 hours if possible, as longer curing times can lead to stronger adhesion.

When This Matters Most

• Delicate or detailed designs: Extra care is essential to avoid breakage during removal.
• Reusable moulds: Gentle handling prolongs the life of your mould and maintains its smooth surface.
